You could do this - 

$string = "my subject <<my-support-id=333333>>";
$pattern = '/\d+/';
preg_match($pattern, $string, $matches);
print_r($matches);

And the output would be Array ( [0] => 333333 )

How about the regex

/<<[^\d]+(\d+)>>/

  • [^\d]+ Negated character class. would match anything other than digits, \d

  • (\d+) Capture group 1 will contain the digits within the << >>

Regex Demo

Test

preg_match("/<<[^\d]+(\d+)>>/", "my subject <<my-support-id=333333>>",$matches);
print_r($matches[1]);
=> 333333

OR

/<<[^=]+=(\d+)>>/

Test

preg_match ( "/<<[^=]+=(\d+)>>/", "my subject <<my-support-id=333333>>",$matches);
print_r($matches[1]);
=> 333333

Try this:

preg_match_all('/\=([0-9]+)>/','my subject <<my-support-id=333333>>', $out, PREG_PATTERN_ORDER);
echo $out[1][0];
